1) the result of wankin' it in the shower; the jizz runs down your hand, and gets stuck to your knuckles

A group of brave, Ugandan Knuckles that go around on VR Chat and ask "Do you know da wae?" and "Where is the queen?" in a very dumb, but a good-sounding voice. If they find a queen, they make clicking noises. If it's a fake queen, they "spit" on the fake queen. So far one of the best memes for January 2018.

Ugandan Knuckles 3: (makes spitting noise)
